Abstract
The effects of incorporating tungsten into the traditional Co–Mo–K/γ–Al2O3 catalysts on the catalytic performances for water–gas shift reaction were investigated. Activity tests showed that W-promoted Co–Mo–K/γ–Al2O3 catalysts exhibited higher activity than W-free Co–Mo–K/γ–Al2O3 catalyst. Raman and H2-TPR studies indicated that part of the octahedrally coordinated Mo–O species on Co–Mo–K catalysts transformed into tetrahedrally coordinated Mo–O species in the presence of W promoter.
